Population Properties of Neutron Stars in the Coalescing Compact Binaries
The Astrophysical Journal, 2021 Abstract We perform a hierarchical Bayesian inference to investigate the population properties of the coalescing compact binaries involving at least one neutron star (NS). With the current gravitational-wave (GW) observation data, we can rule out none of the double Gaussian, single Gaussian, and uniform NS mass distribution models ...

Ultracompact X-ray binaries with He star companions [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT Ultracompact X-ray binaries (UCXBs) are low-mass X-ray binaries with hydrogen-deficient mass donors and ultrashort orbital periods. They have been suggested to be the potential Laser Interferometer Space Antenna (LISA) sources in the low-frequency region. Several channels for the formation of UCXBs have been proposed so far.

CHIME Discovery of a Binary Pulsar with a Massive Nondegenerate Companion
The Astrophysical Journal, 2023 Of the more than 3000 radio pulsars currently known, only ∼300 are in binary systems, and only five of these consist of young pulsars with massive nondegenerate companions.

The scenario of two families of compact stars 1. Equations of state, mass-radius relations and binary systems [PDF]
, 2015 We present several arguments which favor the scenario of two coexisting families of compact stars: hadronic stars and quark stars. Besides the well known hyperon puzzle of the physics of compact stars, a similar puzzle exists also when considering delta ...

Strange quark stars in binaries: formation rates, mergers and explosive phenomena [PDF]
, 2017 The existence of strange quark stars has been proposed many years ago. More recently, the possible co-existence of a first family composed of "normal" neutron stars with a second family of strange quark stars has been proposed as a solution of problems ...

A microquasar shot out from its birth place [PDF]
, 2004 We show that the microquasar LSI+61303 is running away from its birth place in a young complex of massive stars. The supernova explosion that formed the compact object shot out the x-ray binary with a linear momentum of 430 +/- 140 Msun km/s, which is ...

Dynamic normalization for compact binary coalescence searches in non-stationary noise [PDF]
Classical and quantum gravity, 2020 The output of gravitational-wave interferometers, such as LIGO and Virgo, can be highly non-stationary. Broadband detector noise can affect the detector sensitivity on the order of tens of seconds. Gravitational-wave transient searches, such as those for

Great Impostors: Extremely Compact, Merging Binary Neutron Stars in the Mass Gap Posing as Binary Black Holes. [PDF]
Physical Review Letters, 2019 Can one distinguish a binary black hole undergoing a merger from a binary neutron star if the individual compact companions have masses that fall inside the so-called mass gap of 3-5 M_{⊙}?

startrack predictions of the stochastic gravitational-wave background from compact binary mergers [PDF]

Population Synthesis of Black Hole Binaries with Compact Star Companions [PDF]
The Astrophysical Journal, 2021 Abstract We perform a systematic study of merging black hole (BH) binaries with compact star (CS) companions, including black hole–white dwarf (BH–WD), black hole–neutron star (BH–NS), and black hole–black hole (BH–BH) systems. Previous studies have shown that mass transfer stability and common envelope evolution can significantly affect
